Section 6
CABSAD$, CRELAD$–Addressing
Routines
The CABSAD$ routine computes the absolute address for a given address relative to a
location counter. CRELAD$ computes the element name, location counter number, and
address relative to the location number of a caller-specified absolute address.
The following routines are available either as relocatables or common bank absolutes and
can be used in conjunction with D-bank segments above 65K addressing.
When calling the common bank version of the routines, it is necessary to provide a
300-word buffer for their internal use.
6.1. Absolute Addressing Routines
The CABSAD$ routines are called by the MASM procedure C$ABSAD. C$ABSAD is
used to generate the calling sequence for the relocatable version, the common bank
version, or the common bank version using the Auto Switch calling sequence. Section 3
describes the advantages and disadvantages of using the different types of calls.
Calling Format
C$ABSAD[,t] func-code [,p1,p2,p3] [pkt-addr]
error return
normal return
Parameters
t
Type of call to the routine. This parameter is optional and may be omitted. CB or A,
if specified, must be enclosed by apostrophes.
blank Call the relocatable version. This is the default if t is omitted.
'CB' Call the common bank version.
'A' Call the common bank version using the Auto Switch method.
